             Bug #: 55835
           Summary: [TileGX] libgcc doesn't build.
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgcc
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gcc.5.saskwach@spamgourmet.com


gcc/config/tilegx/linux.h in the 4.7.2 source wants to #include <arch/icache.h>
but there is no icache.h anywhere in the source distribution.

I grabbed the arch directory from Tilera's MDE distribution and plopped it into
libgcc's include path and now get this error when trying to build libgcc for
the TileGX:

# If this is the top-level multilib, build all the other
# multilibs.

such file or directory

I've built GCC and binutils already for the TileGX with the following commands:

$ ../binutils-2.23/configure --target=tilegx-redhat-linux --prefix=$PREFIX
--disable-nls
$ make -j9 all
$ make install
and, for GCC...
$ ../gcc-4.7.2/configure  --target=tilegx-redhat-linux --prefix=$PREFIX
--disable-nls --without-headers
$ make -j9 all-gcc
$ make install-gcc

In the GCC build directory, I then ran 
$ make all-target-libgcc
to get the above error.
